Pope Celestine V

Pope Celestine V (1215-19 May 1296), born Pietro Angelerio, was Pope from 5 July to 13 December 1294, succeeding Pope Nicholas IV and preceding Pope Boniface VIII.

Biography
Pietro Angelerio was born in 1215, and in 1244 he founded the Celestine Order while being a monk. On 5 July 1294, Angelerio was consecrated as "Celestine V", and he succeeded Pope Nicholas IV as pope. He retired after a few months in office after passing a decree that allowed popes to abdicate, as he wanted to return to his humble life. Pope Boniface VIII annulled Celestine's acts upon taking office, and Celestine died in 1296.
